DETAILED DESCRIPTION

An embodiment of a Holodeck (collectively called “Holodeck DesignParameters”) provide sufficient energy stimulus to fool the humansensory receptors into believing that received energy impulses within avirtual, social and interactive environment are real, providing: 1)binocular disparity without external accessories, head-mounted eyewear,or other peripherals; 2) accurate motion parallax, occlusion and opacitythroughout a viewing volume simultaneously for any number of viewers; 3)visual focus through synchronous convergence, accommodation and miosisof the eye for all perceived rays of light; and 4) converging energywave propagation of sufficient density and resolution to exceed thehuman sensory “resolution” for vision, hearing, touch, taste, smell,and/or balance.

Based upon conventional technology to date, we are decades, if notcenturies away from a technology capable of providing for all receptivefields in a compelling way as suggested by the Holodeck DesignParameters including the visual, auditory, somatosensory, gustatory,olfactory, and vestibular systems.

In this disclosure, the terms light field and holographic may be usedinterchangeably to define the energy propagation for stimulation of anysensory receptor response. While initial disclosures may refer toexamples of energy and mechanical energy propagation through energysurfaces for holographic imagery and volumetric haptics, all forms ofsensory receptors are envisioned in this disclosure. Furthermore, theprinciples disclosed herein for energy propagation along propagationpaths may be applicable to both energy emission and energy capture.

Many technologies exist today that are often unfortunately confused withholograms including lenticular printing, Pepper's Ghost, glasses-freestereoscopic displays, horizontal parallax displays, head-mounted VR andAR displays (HMD), and other such illusions generalized as“fauxlography.” These technologies may exhibit some of the desiredproperties of a true holographic display, however, lack the ability tostimulate the human visual sensory response in any way sufficient toaddress at least two of the four identified Holodeck Design Parameters.

These challenges have not been successfully implemented by conventionaltechnology to produce a seamless energy surface sufficient forholographic energy propagation. There are various approaches toimplementing volumetric and direction multiplexed light field displaysincluding parallax barriers, hogels, voxels, diffractive optics,multi-view projection, holographic diffusers, rotational mirrors,multilayered displays, time sequential displays, head mounted display,etc., however, conventional approaches may involve a compromise on imagequality, resolution, angular sampling density, size, cost, safety, framerate, etc., ultimately resulting in an unviable technology.

To achieve the Holodeck Design Parameters for the visual, auditory,somatosensory systems, the human acuity of each of the respectivesystems is studied and understood to propagate energy waves tosufficiently fool the human sensory receptors. The visual system iscapable of resolving to approximately 1 arc min, the auditory system maydistinguish the difference in placement as little as three degrees, andthe somatosensory system at the hands are capable of discerning pointsseparated by 2-12 mm. While there are various and conflicting ways tomeasure these acuities, these values are sufficient to understand thesystems and methods to stimulate perception of energy propagation.

Of the noted sensory receptors, the human visual system is by far themost sensitive given that even a single photon can induce sensation. Forthis reason, much of this introduction will focus on visual energy wavepropagation, and vastly lower resolution energy systems coupled within adisclosed energy waveguide surface may converge appropriate signals toinduce holographic sensory perception. Unless otherwise noted, alldisclosures apply to all energy and sensory domains.

When calculating for effective design parameters of the energypropagation for the visual system given a viewing volume and viewingdistance, a desired energy surface may be designed to include manygigapixels of effective energy location density. For wide viewingvolumes, or near field viewing, the design parameters of a desiredenergy surface may include hundreds of gigapixels or more of effectiveenergy location density. By comparison, a desired energy source may bedesigned to have 1 to 250 effective megapixels of energy locationdensity for ultrasonic propagation of volumetric haptics or an array of36 to 3,600 effective energy locations for acoustic propagation ofholographic sound depending on input environmental variables. What isimportant to note is that with a disclosed bi-directional energy surfacearchitecture, all components may be configured to form the appropriatestructures for any energy domain to enable holographic propagation.

However, the main challenge to enable the Holodeck today involvesavailable visual technologies and energy device limitations. Acousticand ultrasonic devices are less challenging given the orders ofmagnitude difference in desired density based upon sensory acuity in therespective receptive field, although the complexity should not beunderestimated. While holographic emulsion exists with resolutionsexceeding the desired density to encode interference patterns in staticimagery, state-of-the-art display devices are limited by resolution,data throughput and manufacturing feasibility. To date, no singulardisplay device has been able to meaningfully produce a light fieldhaving near holographic resolution for visual acuity.

Production of a single silicon-based device capable of meeting thedesired resolution for a compelling light field display may notpractical and may involve extremely complex fabrication processes beyondthe current manufacturing capabilities. The limitation to tilingmultiple existing display devices together involves the seams and gapformed by the physical size of packaging, electronics, enclosure, opticsand a number of other challenges that inevitably result in an unviabletechnology from an imaging, cost and/or a size standpoint.

The embodiments disclosed herein may provide a real-world path tobuilding the Holodeck.

Example embodiments will now be described hereinafter with reference tothe accompanying drawings, which form a part hereof, and whichillustrate example embodiments which may be practiced.

Holographic System Considerations Overview of Light Field EnergyPropagation Resolution

Light field and holographic display is the result of a plurality ofprojections where energy surface locations provide angular, color andintensity information propagated within a viewing volume. The disclosedenergy surface provides opportunities for additional information tocoexist and propagate through the same surface to induce other sensorysystem responses. Unlike a stereoscopic display, the viewed position ofthe converged energy propagation paths in space do not vary as theviewer moves around the viewing volume and any number of viewers maysimultaneously see propagated objects in real-world space as if it wastruly there. In some embodiments, the propagation of energy may belocated in the same energy propagation path but in opposite directions.For example, energy emission and energy capture along an energypropagation path are both possible in some embodiments of the presentdisclosed.

FIG. 1 is a schematic diagram illustrating variables relevant forstimulation of sensory receptor response. These variables may includesurface diagonal 101, surface width 102, surface height 103, adetermined target seating distance 118, the target seating field of viewfield of view from the center of the display 104, the number ofintermediate samples demonstrated here as samples between the eyes 105,the average adult inter-ocular separation 106, the average resolution ofthe human eye in arcmin 107, the horizontal field of view formed betweenthe target viewer location and the surface width 108, the vertical fieldof view formed between the target viewer location and the surface height109, the resultant horizontal waveguide element resolution, or totalnumber of elements, across the surface 110, the resultant verticalwaveguide element resolution, or total number of elements, across thesurface 111, the sample distance based upon the inter-ocular spacingbetween the eyes and the number of intermediate samples for angularprojection between the eyes 112, the angular sampling may be based uponthe sample distance and the target seating distance 113, the totalresolution Horizontal per waveguide element derived from the angularsampling desired 114, the total resolution Vertical per waveguideelement derived from the angular sampling desired 115, device Horizontalis the count of the determined number of discreet energy sources desired116, and device Vertical is the count of the determined number ofdiscreet energy sources desired 117.

A method to understand the desired minimum resolution may be based uponthe following criteria to ensure sufficient stimulation of visual (orother) sensory receptor response: surface size (e.g., 84″ diagonal),surface aspect ratio (e.g., 16:9), seating distance (e.g., 128″ from thedisplay), seating field of view (e.g., 120 degrees or +/−60 degreesabout the center of the display), desired intermediate samples at adistance (e.g., one additional propagation path between the eyes), theaverage inter-ocular separation of an adult (approximately 65 mm), andthe average resolution of the human eye (approximately 1 arcmin). Theseexample values should be considered placeholders depending on thespecific application design parameters.

Further, each of the values attributed to the visual sensory receptorsmay be replaced with other systems to determine desired propagation pathparameters. For other energy propagation embodiments, one may considerthe auditory system's angular sensitivity as low as three degrees, andthe somatosensory system's spatial resolution of the hands as small as2-12 mm.

While there are various and conflicting ways to measure these sensoryacuities, these values are sufficient to understand the systems andmethods to stimulate perception of virtual energy propagation. There aremany ways to consider the design resolution, and the below proposedmethodology combines pragmatic product considerations with thebiological resolving limits of the sensory systems. As will beappreciated by one of ordinary skill in the art, the following overviewis a simplification of any such system design, and should be consideredfor exemplary purposes only.

With the resolution limit of the sensory system understood, the totalenergy waveguide element density may be calculated such that thereceiving sensory system cannot discern a single energy waveguideelement from an adjacent element, given:

${{Surface}\mspace{14mu} {Aspect}\mspace{14mu} {Ratio}} = \frac{{Width}\mspace{14mu} (W)}{{Height}\mspace{14mu} (H)}$${{Surface}\mspace{14mu} {Horizontal}\mspace{14mu} {Size}} = {{Surface}\mspace{14mu} {Diagonal}*\left( \frac{1}{\sqrt{\left( {1 + \left( \frac{H}{W} \right)^{2}} \right.}} \right)}$${{Surface}\mspace{14mu} {Vertical}\mspace{14mu} {Size}} = {{Surface}\mspace{14mu} {Diagonal}*\left( \frac{1}{\sqrt{\left( {1 + \left( \frac{W}{H} \right)^{2}} \right.}} \right)}$${{Horizontal}\mspace{14mu} {Field}\mspace{14mu} {of}\mspace{14mu} {View}} = {2*{{atan}\left( \frac{{Surface}\mspace{14mu} {Horizontal}\mspace{14mu} {Size}}{2*{Seating}\mspace{14mu} {Distance}} \right)}}$${{Vertical}\mspace{14mu} {Field}\mspace{14mu} {of}\mspace{14mu} {View}} = {2*{{atan}\left( \frac{{Surface}\mspace{14mu} {Vertical}\mspace{14mu} {Size}}{2*{Seating}\mspace{14mu} {Distance}} \right)}}$${{Horizontal}\mspace{14mu} {Element}\mspace{14mu} {Resolution}} = {{Horizontal}\mspace{14mu} {FoV}*\frac{60}{{Eye}\mspace{14mu} {Resolultion}}}$${{Vertical}\mspace{14mu} {Element}\mspace{14mu} {Resolution}} = {{Vertical}\mspace{14mu} {FoV}*\frac{60}{{Eye}\mspace{14mu} {Resolultion}}}$

The above calculations result in approximately a 32×18° field of viewresulting in approximately 1920×1080 (rounded to nearest format) energywaveguide elements being desired. One may also constrain the variablessuch that the field of view is consistent for both (u, v) to provide amore regular spatial sampling of energy locations (e.g. pixel aspectratio). The angular sampling of the system assumes a defined targetviewing volume location and additional propagated energy paths betweentwo points at the optimized distance, given:

${{Sample}\mspace{14mu} {Distance}} = \frac{{Inter}\text{-}{Ocular}\mspace{14mu} {Distance}}{\left( {{{Number}\mspace{14mu} {of}\mspace{14mu} {Desired}\mspace{14mu} {Intermediate}\mspace{14mu} {Samples}} + 1} \right)}$${{Angular}\mspace{14mu} {Sampling}} = {{atan}\left( \frac{{Sample}\mspace{14mu} {Distance}}{{Seating}\mspace{14mu} {Distance}} \right)}$

In this case, the inter-ocular distance is leveraged to calculate thesample distance although any metric may be leveraged to account forappropriate number of samples as a given distance. With the abovevariables considered, approximately one ray per 0.57° may be desired andthe total system resolution per independent sensory system may bedetermined, given:

${{Locations}\mspace{14mu} {Per}\mspace{14mu} {Element}\mspace{14mu} (N)} = \frac{{Seating}\mspace{14mu} {FoV}}{{Angular}\mspace{14mu} {Sampling}}$Total  Resolution  H = N * Horizontal  Element  ResolutionTotal  Resolution  V = N * Vertical  Element  Resolution

With the above scenario given the size of energy surface and the angularresolution addressed for the visual acuity system, the resultant energysurface may desirably include approximately 400 k×225 k pixels of energyresolution locations, or 90 gigapixels holographic propagation density.These variables provided are for exemplary purposes only and many othersensory and energy metrology considerations should be considered for theoptimization of holographic propagation of energy. In an additionalembodiment, 1 gigapixel of energy resolution locations may be desiredbased upon the input variables. In an additional embodiment, 1,000gigapixels of energy resolution locations may be desired based upon theinput variables.

Current Technology Limitations Active Area, Device Electronics,Packaging, and the Mechanical Envelope

FIG. 2 illustrates a device 200 having an active area 220 with a certainmechanical form factor. The device 200 may include drivers 230 andelectronics 240 for powering and interface to the active area 220, theactive area having a dimension as shown by the x and y arrows. Thisdevice 200 does not take into account the cabling and mechanicalstructures to drive, power and cool components, and the mechanicalfootprint may be further minimized by introducing a flex cable into thedevice 200. The minimum footprint for such a device 200 may also bereferred to as a mechanical envelope 210 having a dimension as shown bythe M:x and M:y arrows. This device 200 is for illustration purposesonly and custom electronics designs may further decrease the mechanicalenvelope overhead, but in almost all cases may not be the exact size ofthe active area of the device. In an embodiment, this device 200illustrates the dependency of electronics as it relates to active imagearea 220 for a micro OLED, DLP chip or LCD panel, or any othertechnology with the purpose of image illumination.

In some embodiments, it may also be possible to consider otherprojection technologies to aggregate multiple images onto a largeroverall display. However, this may come at the cost of greatercomplexity for throw distance, minimum focus, optical quality, uniformfield resolution, chromatic aberration, thermal properties, calibration,alignment, additional size or form factor. For most practicalapplications, hosting tens or hundreds of these projection sources 200may result in a design that is much larger with less reliability.

For exemplary purposes only, assuming energy devices with an energylocation density of 3840×2160 sites, one may determine the number ofindividual energy devices (e.g., device 100) desired for an energysurface, given:

${{Devices}\mspace{14mu} H} = \frac{{Total}\mspace{14mu} {Resolution}\mspace{14mu} H}{{Device}\mspace{14mu} {Resolution}\mspace{14mu} H}$${{Devices}\mspace{14mu} V} = \frac{{Total}\mspace{14mu} {Resolution}\mspace{14mu} V}{{Device}\mspace{14mu} {Resolution}\mspace{14mu} V}$

Given the above resolution considerations, approximately 105×105 devicessimilar to those shown in FIG. 2 may be desired. It should be noted thatmany devices consist of various pixel structures that may or may not mapto a regular grid. In the event that there are additional sub-pixels orlocations within each full pixel, these may be exploited to generateadditional resolution or angular density. Additional signal processingmay be used to determine how to convert the light field into the correct(u,v) coordinates depending on the specified location of the pixelstructure(s) and can be an explicit characteristic of each device thatis known and calibrated. Further, other energy domains may involve adifferent handling of these ratios and device structures, and thoseskilled in the art will understand the direct intrinsic relationshipbetween each of the desired frequency domains. This will be shown anddiscussed in more detail in subsequent disclosure.

The resulting calculation may be used to understand how many of theseindividual devices may be desired to produce a full resolution energysurface. In this case, approximately 105×105 or approximately 11,080devices may be desired to achieve the visual acuity threshold. Thechallenge and novelty exists within the fabrication of a seamless energysurface from these available energy locations for sufficient sensoryholographic propagation.

Summary of Seamless Energy Surfaces Configurations and Designs forArrays of Energy Relays

In some embodiments, approaches are disclosed to address the challengeof generating high energy location density from an array of individualdevices without seams due to the limitation of mechanical structure forthe devices. In an embodiment, an energy propagating relay system mayallow for an increase the effective size of the active device area tomeet or exceed the mechanical dimensions to configure an array of relaysand form a singular seamless energy surface.

FIG. 3 illustrates an embodiment of such an energy relay system 300. Asshown, the relay system 300 may include a device 310 mounted to amechanical envelope 320, with an energy relay element 330 propagatingenergy from the device 310. The relay element 330 may be configured toprovide the ability to mitigate any gaps 340 that may be produced whenmultiple mechanical envelopes 320 of the device are placed into an arrayof multiple devices 310.

For example, if a device's active area 310 is 20 mm×10 mm and themechanical envelope 320 is 40 mm×20 mm, an energy relay element 330 maybe designed with a magnification of 2:1 to produce a tapered form thatis approximately 20 mm×10 mm on a minified end (arrow A) and 40 mm×20 mmon a magnified end (arrow B), providing the ability to align an array ofthese elements 330 together seamlessly without altering or collidingwith the mechanical envelope 320 of each device 310. Mechanically, therelay elements 330 may be bonded or fused together to align and polishensuring minimal seam gap 340 between devices 310. In one suchembodiment, it is possible to achieve a seam gap 340 smaller than thevisual acuity limit of the eye.

FIG. 4 illustrates an example of a base structure 400 having energyrelay elements 410 formed together and securely fastened to anadditional mechanical structure 430. The mechanical structure of theseamless energy surface 420 provides the ability to couple multipleenergy relay elements 410, 450 in series to the same base structurethrough bonding or other mechanical processes to mount relay elements410, 450. In some embodiments, each relay element 410 may be fused,bonded, adhered, pressure fit, aligned or otherwise attached together toform the resultant seamless energy surface 420. In some embodiments, adevice 480 may be mounted to the rear of the relay element 410 andaligned passively or actively to ensure appropriate energy locationalignment within the determined tolerance is maintained.

In an embodiment, the seamless energy surface comprises one or moreenergy locations and one or more energy relay element stacks comprise afirst and second side and each energy relay element stack is arranged toform a singular seamless energy surface directing energy alongpropagation paths extending between one or more energy locations and theseamless energy surface, and where the separation between the edges ofany two adjacent second sides of the terminal energy relay elements isless than the minimum perceptible contour as defined by the visualacuity of a human eye having better than 20/40 vision at a distancegreater than the width of the singular seamless energy surface.

In an embodiment, each of the seamless energy surfaces comprise one ormore energy relay elements each with one or more structures forming afirst and second surface with a transverse and longitudinal orientation.The first relay surface has an area different than the second resultingin positive or negative magnification and configured with explicitsurface contours for both the first and second surfaces passing energythrough the second relay surface to substantially fill a +/−10 degreeangle with respect to the normal of the surface contour across theentire second relay surface.

In an embodiment, multiple energy domains may be configured within asingle, or between multiple energy relays to direct one or more sensoryholographic energy propagation paths including visual, acoustic, tactileor other energy domains.

In an embodiment, the seamless energy surface is configured with energyrelays that comprise two or more first sides for each second side toboth receive and emit one or more energy domains simultaneously toprovide bi-directional energy propagation throughout the system.

In an embodiment, the energy relays are provided as loose coherentelements.

Introduction to Component Engineered Structures Disclosed Advances inTransverse Anderson Localization Energy Relays

The properties of energy relays may be significantly optimized accordingto the principles disclosed herein for energy relay elements that induceTransverse Anderson Localization. Transverse Anderson Localization isthe propagation of a ray transported through a transversely disorderedbut longitudinally consistent material.

This implies that the effect of the materials that produce the AndersonLocalization phenomena may be less impacted by total internal reflectionthan by the randomization between multiple-scattering paths where waveinterference can completely limit the propagation in the transverseorientation while continuing in the longitudinal orientation.

Of significant additional benefit is the elimination of the cladding oftraditional multi-core optical fiber materials. The cladding is tofunctionally eliminate the scatter of energy between fibers, butsimultaneously act as a barrier to rays of energy thereby reducingtransmission by at least the core to clad ratio (e.g., a core to cladratio of 70:30 will transmit at best 70% of received energytransmission) and additionally forms a strong pixelated patterning inthe propagated energy.

FIG. 5A illustrates an end view of an example of one such non-AndersonLocalization energy relay 500, wherein an image is relayed throughmulti-core optical fibers where pixilation and fiber noise may beexhibited due to the intrinsic properties of the optical fibers. Withtraditional multi-mode and multi-core optical fibers, relayed images maybe intrinsically pixelated due to the properties of total internalreflection of the discrete array of cores where any cross-talk betweencores will reduce the modulation transfer function and increaseblurring. The resulting imagery produced with traditional multi-coreoptical fiber tends to have a residual fixed noise fiber pattern similarto those shown in FIG. 3.

FIG. 5B, illustrates an example of the same relayed image 550 through anenergy relay comprising materials that exhibit the properties ofTransverse Anderson Localization, where the relayed pattern has agreater density grain structures as compared to the fixed fiber patternfrom FIG. 5A. In an embodiment, relays comprising randomized microscopiccomponent engineered structures induce Transverse Anderson Localizationand transport light more efficiently with higher propagation ofresolvable resolution than commercially available multi-mode glassoptical fibers.

There is significant advantage to the Transverse Anderson Localizationmaterial properties in terms of both cost and weight, where a similaroptical grade glass material, may cost and weigh upwards of 10 to100-fold more than the cost for the same material generated within anembodiment, wherein disclosed systems and methods comprise randomizedmicroscopic component engineered structures demonstrating significantopportunities to improve both cost and quality over other technologiesknown in the art.

In an embodiment, a relay element exhibiting Transverse AndersonLocalization may comprise a plurality of at least two differentcomponent engineered structures in each of three orthogonal planesarranged in a dimensional lattice and the plurality of structures formrandomized distributions of material wave propagation properties in atransverse plane within the dimensional lattice and channels of similarvalues of material wave propagation properties in a longitudinal planewithin the dimensional lattice, wherein localized energy wavespropagating through the energy relay have higher transport efficiency inthe longitudinal orientation versus the transverse orientation.

In an embodiment, multiple energy domains may be configured within asingle, or between multiple Transverse Anderson Localization energyrelays to direct one or more sensory holographic energy propagationpaths including visual, acoustic, tactile or other energy domains.

In an embodiment, the seamless energy surface is configured withTransverse Anderson Localization energy relays that comprise two or morefirst sides for each second side to both receive and emit one or moreenergy domains simultaneously to provide bi-directional energypropagation throughout the system.

In an embodiment, the Transverse Anderson Localization energy relays areconfigured as loose coherent or flexible energy relay elements.

Considerations for 4D Plenoptic Functions Selective Propagation ofEnergy Through Holographic Waveguide Arrays

As discussed above and herein throughout, a light field display systemgenerally includes an energy source (e.g., illumination source) and aseamless energy surface configured with sufficient energy locationdensity as articulated in the above discussion. A plurality of relayelements may be used to relay energy from the energy devices to theseamless energy surface. Once energy has been delivered to the seamlessenergy surface with the requisite energy location density, the energycan be propagated in accordance with a 4D plenoptic function through adisclosed energy waveguide system. As will be appreciated by one ofordinary skill in the art, a 4D plenoptic function is well known in theart and will not be elaborated further herein.

The figure shows ray traces of an energy surface 600 to aviewer 620 in describing how the rays of energy converge in space 630from various positions within the viewing volume. As shown, eachwaveguide element 610 defines four dimensions of information describingenergy propagation 640 through the energy surface 600. Two spatialdimensions (herein referred to as x and y) are the physical plurality ofenergy locations that can be viewed in image space, and the angularcomponents theta and phi (herein referred to as u and v), which isviewed in virtual space when projected through the energy waveguidearray. In general, and in accordance with a 4D plenoptic function, theplurality of waveguides (e.g., lenslets) are able to direct an energylocation from the x, y dimension to a unique location in virtual space,along a direction defined by the u, v angular component, in forming theholographic or light field system described herein.

The plenopic 4D function through the surface from an energy directingsurface provides for two spatial coordinates x_(l),y_(l) from a firstplane comprising energy locations and directed through a secondcoordinate along a second plane comprising waveguiding parametersu_(l),v_(l) defining a vector of an energy propagation pathƒ_(l)(x_(l),y_(l),u_(l),v_(l)). In consideration of a plurality ofenergy directing surfaces, the plenoptic 5D function provides for threespatial coordinates x_(l),y_(l),z_(l) from a first coordinate comprisingone or more energy locations and directed through a second coordinatealong a plane comprising waveguiding parameters u_(l),v₁ defining avector of an energy propagation path ƒ₁(x_(l),y_(l),z_(l),u_(l),v_(l)).For each of 4D or 5D, additional variables for time and colorƒ_(l)(λ_(l),t_(l)) may be considered and assumed to be inclusive of anyof the plenoptic functions as necessary for an application even when notexplicitly noted for simplicity of the function and discussion. For theavoidance of doubt, the reference to an energy directing surface is forexemplary purposes only and may comprise any additional point, location,direction, or plane in space for the localization of a 5D coordinate,and collectively referred to as an energy “directing surface”.

FIG. 8 is a flow chart diagram illustrating an embodiment of a process800 for determining four dimensional (4D) plenoptic coordinates forcontent data. The process 800 may include a step 802 in which contentdata is received, which may include any signal perceptible by a visual,audio, textural, sensational, or olfactory sensor. FIG. 9 is a schematicdiagram illustrating an embodiment of the content data, which mayinclude at least one of the following: an object location, a materialproperty (such as material properties 906, 907, and 908), a virtuallight source 904, geometry 902 at non-object location, content out ofthe reference surface, a virtual camera position 914, a segmentation 910of objects, background texture 912, and layered contents.

Referring to FIGS. 8 and 9, the process 800 may further include a step804 in which locations of data points are determined with respect to afirst surface 920 to creating a digital volumetric representation 922 ofthe content data. The first surface 920 may be used as a referencesurface for defining the locations of data points in space. In anembodiment, the process 800 may further include a step 806 in which 4Dplenoptic coordinates of the data points are determined at a secondsurface by tracing the locations of the data points in the volumetricrepresentation to the second surface where a 4D function is applied. Inan embodiment, the process 800 may further include a step 808 in whichenergy source location values are determined for 4D plenopticcoordinates that have a first point of convergence.

The content data received in step 802 may include N views, where N isone or more. A single view may be presented with or without a depthchannel. Stereoscopic views may be presented with or without a depthchannel. Multi-view imagery may be presented with or without a depthchannel. Further, a 4D light field may be presented with or without adepth channel.

The tracing of step 806 may use prior knowledge of a calibrated geometryof an energy system, which may be stored in memory as a global model oran individually characterized system or some combination of the twomethodologies.

In an embodiment, the mapping between the input data and the outputenergy source provides a methodology to accurately map between variousbitrate sources. The tracing of step 806 provides the ability to inferthe full volumetric 4D data set from the above listed partial samples.Depth information either needs to be provided or calculated from theavailable data. With the depth information known or calculated, the Nview(s) may be inverse traced by triangulation of the samples from theknown volumetric presentation based upon depth coordinate into the 4Dspace.

The triangulation may assume that each available energy source locationin the N source content are representative of a energy source locationfor each energy waveguide in the event that a mapping between energywaveguide and energy source location format resolution are provided. Inthe event that the N source content resolution are lower,super-resolution or scaling algorithms may be implemented. In the eventthat the resolution of the N source image(s) are higher than the numberof energy waveguides in the energy directing device, interpolationbetween super-sampled energy source locations may be performed toproduce higher amount of energy source locations per energy waveguide inthe resultant 4D inverse ray trace.

The above assumes distance information may be determined from the depthmaps which may or may not be accurate depending on the form of depthinformation provided or calculated, and with the distance informationknown or assumed, the distance information in combination with the x-yenergy source location coordinate and the (u,v) angular information asdetermined by the energy directing device properties may then beconsidered a 4D or 5D light field with limited imaging data samples. Theimaging samples, based upon the distance information, are triangulatedback to the appropriate energy source locations that may exist behindeach energy waveguide respectively, and missing data may be generated instep 808 through the disclosures contained herein.

Referring to FIGS. 7C, 8, 9, 10 in an embodiment, the energy locationsmay be located in the first surface 920, and the second surface where a4D function is applied may correspond to a waveguide system 7100 of anenergy directing device, and energy is operable to be directed throughthe waveguide system according to the 4D plenoptic coordinates of thedata points to form a detectable volumetric representation of thecontent data.

In an embodiment, the process 800 may further comprise a step 810, inwhich energy source location values are determined for 4D coordinatesthat have a first point of convergence. To provide an exampleimplementation of the present disclosure, FIG. 11 illustrates anembodiment of an energy directing device 1000 going through a tracingprocess where content data in the form of an image 1002 is provided witha distance position 1004, which may be provided or calculated, within adetermined minimum position 1006 and maximum position 1008 in referenceto the energy locations 1010. In an embodiment, the energy locations1010 may comprise an energy directing device surface. The known geometryfrom the energy locations 1010 defined by the 4D plenoptic functionallows for the triangulation of a point 1014 on the virtual surface ofthe image 1002 to be traced back along rays 1016 to specific energylocations 1018, each having a unique x-y coordinate. Missing samples maybe computationally calculated based upon the available informationcontained within the dataset.

When additional N samples are provided, the same methodology is appliedwith the additional multi-perspective imaging data producing a richerset of inverse ray traced samples and provide superior holographicresults. The depth information from a multiple N samples may be providedthrough a single depth map, or up to N, or greater than N depth mapswith a known mapping between the source location (the N+X perspective)and the source depth map (the N+X depth map) to ensure appropriateinverse ray tracing is performed.

In the event that a singular depth map for the, for example, center Nperspective is provided, the additional depth maps may be interpolatedby calculating for the disparity between each of the adjacent views toaccurately map the source and target location between the N and the N+Xviewpoints. With this method, it is possible to inverse ray trace theappropriate view dependent mapping to the 4D light field such that thecorrect perspective(s) are projected to the appropriate waveguidecoordinates and results in the viewer's ability to maintain the correctview dependencies in the associated viewpoints.

The encoder and decoders are robust and may interpret multiple datatypes to include, but not limited to, 2D/flat files, 2D with depth,stereoscopic, stereoscopic with single depth channel, stereoscopic withdual depth channel, N+X multi-view with no depth, N+X multi-view withN+Y depth, geometric or vector based scene files that may includetextures, geometry, lighting, material properties and the like toreconstruct an environment, deep imaging files wherein multiple RGBAZvalues may be provided for each x-y coordinate, 4D or 5D (4D plus depth)light fields, or provided as a N+X view plus N+Y delta channel datasetwherein the depth channel provides a lower bandwidth methodology foronly rendering a certain amount of energy source location data asrequired for a determined energy directing device field of view. Theprocessors are able to inverse ray trace at up to, or exceeding,real-time speeds, in order to provision the appropriate 4D light fieldto present to the viewer with and without world coordinate locations,with and without compensated minimum and maximum projected worldlocations and in consideration of the energy directing device intrinsicas characterized and/or designed.

In an embodiment, the process 800 may further comprise a step 812, inwhich a mapping between energy locations 7122 on a first side of thewaveguide system 7100 and the angular directions of the energypropagation paths 7120 from the waveguide element 7100 on a second sideof the waveguide system 7100 is applied. Doing so may allow a pluralityof energy locations on the first side of the waveguide system 7100corresponding to the 4D plenoptic coordinates of the data points to bedetermined.

FIG. 12 is a schematic diagram of a processing system 1200 comprising adata input/output interface 1201 in communication with a processingsubsystem having a sensory data processor 1202, a vectorization engine1204, and a tracing engine 1206. It is to be appreciated that thesensory data processor 1202, the vectorization engine 1204, and thetracing engine 1206 may be implement on one or more processors, whetherindividually or any combination thereof. Step 802 of the process 800 mayinput content data through the data input/output interface 1201 to theprocessing subsystem 1220. Step 804 may be performed by the sensory dataprocessor 1202 to create a volumetric representation of the contentdata. Step 806

In an embodiment, applying the mapping may comprise calibrating for adistortion in the waveguide system 7100, which may further comprisecalibrating for at least one distortion selected from a group consistingof: a spatial distortion, angular distortion, intensity distortion, andcolor distortion.

In an embodiment, the energy directing device may further comprise arelay system 6110 on the first side of the waveguide system 7100, therelay system having a first surface 6116 adjacent to the waveguidesystem 7100, and the energy locations 7112 on the first side of thewaveguide system may be positioned adjacent to a second surface 6114 ofthe relay system 6110.

In an embodiment, applying the mapping may include calibrating for adistortion in the waveguide system 7100. In an embodiment, applying themapping may include calibrating both for a distortion in the relaysystem 6110 and a distortion in the waveguide system 7100. In anembodiment. the distortion to be calibrated may include at least onedistortion selected from a group consisting of: a spatial distortion,angular distortion, intensity distortion, and color distortion.

In an embodiment, a portion of the method may be carried out in realtime, or the method may be entirely carried out in real time, or atleast two portions of the method may be carried out in different timeperiods.

2D to Light Field Conversion

In an embodiment, content data may comprise data points in a twodimensional (2D) space, and determining locations of step 704 maycomprise applying a depth map to the data points in a two dimensionalspace.

There are several methods to convert two-dimensional or flat imageryinto light field data. These include the estimation of depth informationthrough depth from motion analysis, a provided depth channel throughmanual or rendered means, or the manual creation of disparity, depth,occlusion, geometry and/or any other methodology known as standard forvisual effects content creation to reproduce the full light fieldthrough regeneration of the entire environment through manual andautomated processes.

In a first embodiment, a system that includes a real-time or offlineprocessor to perform estimation of depth from available energy sourcelocation information is possible. This may be performed at the energydirecting device, as a set top box or as an offline process. Additionalcomputation for missing volumetric data may be performed leveragingtemporal information and/or state of the art texture synthesis or othertechnologies known in the art.

In a second embodiment, depth information is provided as an image streamand may be embedded into the image format. Similarly, additionalcomputation may be performed for missing volumetric data.

In a third embodiment, an artist or a process is leveraged to generatethe missing environmental information which may include a process toisolate or segment each object in a scene, track said objects over timemanually, semi-automatically or automatically, place objects into spaceleveraging disparity space, energy directing device space, optical spaceor world coordinates, synthesizing background and foreground missinginformation through visual effects processes known in the art forreconstruction of backgrounds, transparencies, edge details, etc. toregenerate the environment. For the avoidance of doubt, the implementedprocesses may be any, none or all of the listed embodiments for thereconstruction of these environments. The generated environmentalinformation should include as much of the missing information aspossible as determined by the energy directing device angles of view,and these angles of view may be known by the artist to ensure thatappropriate occlusion and view dependent information is generatedappropriately.

Additionally, the surface model for each object in the scene may begenerated, either as a partial model or as a completely built model andtextures from the image data are projected onto the surfaces of thegeometry to provide appropriate shape for the following inverse raytracing.

Additionally, material properties may be calculated or manuallyintroduced to ensure that view dependent lighting may be introduced withvirtual illumination sources to further increase the accuracy of theregeneration of the 4D light field.

Further, the addition of CG or synthetic content may be introduced toaugment the existing converted materials. The addition of volumetricdata may also be incorporated. The inter-mixing of N+X content may beintroduced as well to provide a seamless blend between CG, 2D,stereoscopic, multiview and/or 4D media into a single composite.

The resultant 2D to light field converted content may be retained as ageometric scene file including geometry, textures, lighting, materials,etc. as indicated in the CG scene itself, rendered as N+X views with N+Ddepth channels, rendered as a 4D or 5D (4D+depth) light field, a deepimage which is a format that allows for multiple RGBAZ samples per x-yenergy source location coordinate with or without a limitation ofstacking of Z samples per x-y coordinate, or provided as a N+X view plusN+Y delta channel dataset wherein the depth channel provides a lowerbandwidth methodology for only rendering a certain amount of energysource location data as required for a determined energy directingdevice field of view. Tools may be provided to allow for the generationof all, some or one of these respective output formats.

Stereoscopic and Multi-View to Light Field Conversion

The process from above leveraging single view content may be applied tostereoscopic and multi-view materials. The estimation of depthinformation is obtained through depth from motion analysis, as well asfrom stereoscopic, multi-view and/or disparity analysis, a provideddepth channel or provided depth channels through manual or renderedmeans, or the manual creation of disparity, depth, occlusion, geometryand/or any other methodology known as standard for visual effectscontent creation to reproduce the full light field through regenerationof the entire environment through manual and automated processes andleveraging the appropriate data to further retain the view dependentcontent as available in the provided imaging materials.

In an embodiment, the content data received in step 102 may comprisedata points in a three dimensional (3D) space, and determining locationsmay comprise adjusting the data points in the 3D space.

In an embodiment, adjusting the data points in the 3D space may includeapplying a depth map to the data points in the 3D space, adding new datapoints, reconstructing occluded data points, or any combination thereof.

The significant advantage to this approach exists in that the accuracyof stereoscopic disparity estimation is far greater than from motionparallax or other similar 2D estimation processes alone. Further theimage quality of the resultant converted 4D light field is more accuratedue to the availability of some of the view dependent conditions,including but not limited to illumination, transparencies, materials,occlusion, etc.

The ability to retain the explicit angular dependencies of themulti-view image data relies on the ability to calculate the surfacenormals in relation to the center viewpoint camera, or some otherdefined center point. With these normals and disparity or depthinformation known, it is possible to interpolate between viewpointsbased upon energy directing device angle of view, which is then eitherdirectly applied to the inverse ray tracing, or synthesized as a portionof the texture synthesis during the inverse ray tracing.

For brevity, all of the previously disclosed methodologies for thereconstruction of 2D to light field imagery may be applied to thereconstruction of stereoscopic or multi-view datasets.

Generation of N×N RGB Images from 4D or 5D Light Fields

By leveraging 4D or 5D light fields, it is possible to generate N×N orany value of up to N×N number of RGB multi-view images. This process isaccommodated by considering each bottom left coordinate under eachwaveguide, assuming a square grid, the 0,0 position, and the top rightposition as the N,N position. The grid is only exemplary and any othermapping methodology may be leveraged. For each 0,0 to N,N position, itis possible to form full resolution images from the light field with thewidest possible depth of field based upon the capture system leveragedwherein each waveguide in the array is considered a single energy sourcelocation and each coordinate under each waveguide is a single energysource location of the larger energy source location array for eachcomplete image from 0,0 to N,N respectively. This may be repeated for a5D light field for the depth information as well. In this fashion, it ispossible to easily translate between the 4D or 5D light field to anysubset of the dataset that is desired for various distribution reasonsto include 2D, stereoscopic, multi-view, point cloud, CG scene file, orany other desired combination of data that may be derived from the 4D or5D light field. For non-regular or square packed 4D or 5D structures,further interpolation is required to align energy source locations to aregular grid, or a linear mapping between energy source locations andnon-square packed structures may be implemented wherein the resultantimages may not appear rectilinear and may also contain energy sourcelocation artifacts.

FIG. 11 exemplifies the methodology to convert from a 4D or 5D lightfield into multiple viewpoints by arranging the energy locations 1102from underneath of each energy waveguide element 1104 according toenergy waveguide element position and energy location coordinaterespectively. This provides the ability to seamlessly transfer betweenlight field and smaller datasets seamlessly.

N+X RGB and N+Y Depth Datasets

The ideal dataset format that provides the highest quality with thebalance of data transmission size includes the use of N+X RGB and N+YDepth+vectorized channels wherein N+X RGB information contains N RGBimages that may represent a certain resolution and format, and X thatmay represent a different resolution and format for RGB data to includelower resolutions, delta information and the like, and N+YDepth+vectorized channels that contains N depth+vectorized channels thatmay represent a certain resolution and format and Y that may represent adifferent resolution and format for depth+vector data to include lowerresolutions, delta information and the like.

The number of N+X views may be generated on a regular grid, from aradius around a center point with or without a center view, frommultiple radii around a center point with or without a center view, orany methodology to determine the mapping of the number of views and theassociated packing or perspective locations. The configuration for theperspectives may be contained in the metadata of the file, or thedepth+vectorized channels provided may include a direct mapping to worldcoordinates such that the imaging data aligns to the same coordinate inXYZ space without other necessary metadata.

4D Disk Inversion and Energy Directing Device Compatibility Processing

For any data captured with a plenoptic or light field 4D or 5D system,including potentially those captured with virtual rigs with opticalsimulation of a 4D or 5D light field system, the resultant fly's eyeperspectives contain discs that represent the uv vectors for the lightfield. However, these coordinates assume energy focusing elements thatmay not exist in an energy directing device. In the proposed energydirecting device solution, the focusing elements may be the viewer'seye, and the mapping between the capture system and the mapping betweenthe original capture methodology and the viewed energy directing deviceare no longer correct.

To invert this and correct for the additionally missing energy directingelement in the system when compared to the capture system, it ispossible to individually flip each disc independently, wherein the x-ylocation of each (u,v) coordinate is retargeted based upon the centerpoint of each waveguide respectively. In this fashion, the inversion ofthe image that forms as a result of the main waveguide is inverted andallows for the light field energy directing device to project the raysin the correct x-y-u-v orientation.

A further embodiment of this may implement a hardware modificationwherein leveraging an energy waveguide array provides a direct inversionof every presented energy waveguide energy source location. For lightfield energy directing devices, this is advantageous to have a directmapping between a potential capture system and energy directing device.This may further be advantageous an embodiment comprising HMD systems orvolumetric opacity energy directing devices such that a group of energywaveguides in the overall array may be eliminated by removing thenecessity to relay additional times for accurate x-y-u-v coordinates.

Further, not all light fields are identical. They may be captured withdiffering NAs, FOVs, N values, optical prescriptions, etc. Theintrinsics and extrinsics of the input light field data may beunderstood and convert to the energy directing device characteristics.This may be performed by embodiments contained within this disclosurefor universal parametization of holographic and light field data.

Universal Parameterization of Holographic Sensory Data Transport ThroughInverse EnergyTracing and Vectorization of Sensory Properties for anEnergy Directing System

The plenopic 4D function through the surface from an energy directingsurface provides for two spatial coordinates x_(l),y_(l) from a firstplane comprising energy locations and directed through a secondcoordinate along a second plane comprising waveguiding parametersu_(l),v_(l) defining a vector of an energy propagation pathƒ_(l)(x_(l),y_(l),u_(l),v_(l)). In consideration of a plurality ofenergy directing surfaces, the plenoptic 5D function provides for threespatial coordinates x_(l),y_(l),z_(l) from a first coordinate comprisingone or more energy locations and directed through a second coordinatealong a plane comprising waveguiding parameters u_(l),v_(l) defining avector of an energy propagation pathƒ_(l)(x_(l),y_(l),z_(l),u_(l),v_(l)). For each of 4D or 5D, additionalvariables for time and color ƒ_(l)(λ_(l),t_(l)) may be considered andassumed to be inclusive of any of the plenoptic functions as necessaryfor an application even when not explicitly noted for simplicity of thefunction and discussion. For the avoidance of doubt, the reference to anenergy directing surface is for exemplary purposes only and may compriseany additional point, location, direction, or plane in space for thelocalization of a 5D coordinate, and collectively referred to as anenergy “directing surface”.

Along a first vector of an energy propagation path, a plurality ofintersection points comprising convergence of energies may occurtogether with additional energy propagation paths. At this intersectionpoint, a 3D point or depth parameter forms at location X_(l),Y_(l),Z_(l)among the plurality of energy propagation paths with the 4D or 5Dfunctions, wherein the 3D point of convergence X_(l),Y_(l),Z_(l) amongthe plurality of energy propagation paths, where for each x_(l),y_(l) orx_(l),y_(l),z_(l) coordinate contained within the energy directingsurface or surfaces, there is only a single u_(l),v_(l) propagation paththat forms between a first coordinate and the converging 3D point. The4D function ƒ_(Z)(x_(l),y_(l),u_(l),v_(l)) or 5D functionƒ_(Z)(x_(l),y_(l),z_(l),u_(l),v_(l)) collectively define all 4Dx_(l),y_(l), or 5D x_(l),y_(l),z_(l) coordinates and commensurateu_(l),v_(l) propagation paths that exist for each converging point atX_(l),Y_(l),Z_(l).

At a first 5D coordinate resulting from the convergence of energiesalong a plurality of energy propagation paths through the energydirecting surface X_(l),Y_(l),Z_(l), the coordinate may represent apoint within a larger object, volume, particle or localized energyparameter, wherein converging energies at additional coordinatesproximate to the first 5D coordinate may exhibit additional vectorizedproperties for sensory energies within an environment or holographicdataset. These vectorized properties may comprise information for each5D coordinate, for each energy location coordinate within the 4Ddataset, for regions within either of the 4D or 5D datasets, or othersub-sets of coordinates comprising the energy surface.

In an embodiment, the universal parameterization of 4D and 5Dholographic sensory energy properties for propagation of visual,auditory, somatosensory, gustatory, olfactory, vestibular or otherdesired energies for sensory system response for raster and vector 2D,3D, 4D and 5D datasets are disclosed, wherein the 2D data may comprise asingle angular sample, 3D data may comprise two or more angular samplesin a single dimension, 4D data may comprise a plurality of angularsamples in two dimensions, or 5D data may comprise a plurality ofangular samples in three or more dimensions, in reference to the secondcoordinate of the second plane of the 4D energy directing surface.

In an embodiment, the somatosensory system may be defined based upon thecomponents that define sensitivity including mechanoreceptors fortextures with a pressure sensitivity range in the skin that may benormalized between 50 Hz to 300 Hz, thermoreceptors with a temperaturesensitivity range in the skin that may be normalized between 0° c. to50° c. (although this range may be much wider range with upper and lowerbounds defined by the extremes of temperature) or surface deformabilitydefining the range of viscoelastic behaviors of a material measure bothviscous and elastic characteristics when undergoing deformations betweenstress and strain over time which provides for a multiplicity of physicsincluding variables for time, strain, modulus, among other dynamics, andfor the purposes of this disclosure is simplified to a dimensionlessnormalized scale with a value of 0 for unmovable solids such as granite,and 1 for low viscosity liquids such as water. Those skilled in the artwill understand that the actual vectors provided will comprise thenecessary physics to appropriately define the viscoelasticity of thematerial, and normalized for exemplary purposes only.

Finally, state of the art advances in artificial electronic sensingincluding gustatory and olfactory devices demonstrate a viable path tofurther vectorizing the sensory parameters disclosed for the Holodeckdesign parameters, as well as enable the electronic reproduction ofartificial taste and smell through a holographic waveguiding means asdescribed herein. Artificial electronic taste and smell receptors havemade considerable progress through emerging nanodevices, whereinfrequency-based artificial taste receptors using an enzymatic biosensorto sample the intensity of chemical stimulus through the encoding andconversion to frequency based pulses to both repeatedly and accuratelydetect taste as frequencies of the sampled chemical compositions througha pattern recognition system resulting in the detection of the tastesthat compose the human palate. It is believed that the technology may beextended to all types of detectable tastes and similar advances inartificial olfactory system have demonstrated digital interfaces forstimulating ones smell receptors using weak electrical pulses targetingthe nasal conchae with ongoing studies to further parameterize thepatterns contained within frequencies of particular olfactory responsesthrough variation in electrical signals.

With the path established for the arbitrary generation of frequenciesand complex electronic patterns to represent olfactory, gustatory andother sensory system, in one embodiment, the acuity response for tastemay be vectorized to comprise a normalized scale for each ofelectronically controlled parameters along a scale from 0 to 1 torepresent the minimum and maximum gustatory response to saturate theaverage human's 2,000-8,000 taste buds, potentially comprising but notlimited to vectors for sourness, saltiness, bitter (spiciness),sweetness, and savoriness (unmami) wherein the vector and the spatialcoordinate of the vectorized signals may inform the production for thecomplex olfactory implementations.

In another embodiment, the acuity response for smell may be furthervectorized to comprise a normalized scale for each of electronicallycontrolled parameters along a scale from 0 to 1 to represent the minimumand maximum olfactory response to saturate the average human's 10 cm′ ofolfactory epithelium, for each of the highly complex olfactory spacespotentially comprising but not limited to vectors for fragrant, fruity,citrus, woody (resinous), chemical, sweet, mint (peppermint), toasted(nutty), pungent and decayed wherein the vector and the spatialcoordinate of the vectorized signals may inform the production for thecomplex olfactory implementations.

Each of these vectors may provide the normalized values representingthese patterns for taste, smell or other sensory domains, converted to awave, amplitude, magnitude or other attribute as required for theappropriate application of the provided vectorized values. While thesense of smell and taste are two of the most highly debased senseswithin the sensory system, with parameterized values to vectorizecomplex amalgamations, it is additionally possible in an embodiment toprovide for user based interactive control over the sensitivity of anysuch sensory energy to provide for customization of individualization ofeach of visual, auditory, somatosensory, gustatory, olfactory,vestibular or other desired sensory system responses.

In an embodiment, each of the represented sensory albedo energy valuesof the sample may additionally comprise extrinsic energy attributesbaked into the single sample value representing the additive result ofeach provided sample respective of other external samples, properties orenvironmental conditions. In this configuration, the compound samplevalue may or may not exhibit latent attributes of other energies fromother samples in a physically based or simulated environment. The mostefficient and pure methodology to transmit the parameterized andreconstructed holographic dataset is based upon the singular intrinsicsample information providing for simplified and lower bandwidthfrequency information, although this is not always possible to receiveoutside of entirely synthetic environments, particularly for physicallybased imaging or acoustic systems. In any real-world environment, thereis always some amount of extrinsic contribution to the resultant sampleinformation. Certain systems like the Light Stage, or other systemsknown in the art to facilitate the estimation of reflectance, shape,texture, and motion capture leverage some form of structuredillumination and one or more imaging devices which provide for thedirect or indirect analysis of the albedo, depth information, surfacenormal and bidirectional scattering distribution surface properties.

The bidirectional scattering distribution function (BSDF) is ageneralized superset of the bidirectional transmittance distributionfunction (BTDF), the bidirectional texture function (BTF), and thebidirectional reflectance distribution function (BRDF), which are oftenrepresented by the generalized function ƒ_(r)(w_(i),w_(r)), collectivelyact as a model to parameterize and identify surface properties incomputer graphics and vision algorithms known in the art. The functiondescribes how visible light is reflected, transmitted or otherwiseinteracts with a surface given an incoming incident direction w_(i) andoutgoing reflected or transmitted direction w_(r) for an energypropagation path, where the surface normal is perpendicular to thetangent of the object surface and the function describes the ratio ofreflected radiance exiting along the outgoing path w_(r) to theirradiance incident on the surface along the incoming path w_(i),wherein each of w_(i),w_(r) may comprise a 4D function to define aparameterized azimuth and zenith angle for each of the incoming lightpath and the exiting light path.

The functions may further be articulated for a first location x_(i) ofenergy λ_(i) striking a surface, and exit after material propertiesinternally scatter the energy to a second location x_(r) of energy λ_(r)to account for visible wavelength effects like iridescence,luminescence, subsurface scattering, non-local scattering effects,specularity, shadowing, masking, interreflections, or the like,resultant output energy based upon material properties of a surface, theinput energies and locations, the output energies and locations acrossthe surface of an object, volume, or point.

Therefore, the generalized properties to describe how energy istransported between any two energy rays that strike a surface, toinclude wavelength or frequency dependency and spatially varyingmaterial properties or surfaces, may be represented as a 10D function,and specified as ƒ_(r) (λ_(i),x_(i),w_(i),λ_(r),x_(r),w_(r)) for each orany of the available or provided samples within a dataset to account forinput energy, the impact of a vectorized surface profile, and the outputreflected, refracted, specular, transmitted, scattered, diffused, orother material property result from any energy domain given thegeneralization of the function ƒ_(r).

In consideration now of the energy directing surface, the plenopic 4Dfunction provides for two spatial coordinates x_(l),y_(l) from a firstplane comprising energy locations and directed through a secondcoordinate along a second plane comprising waveguiding parametersu_(i),v_(i) defining a vector of an energy propagation pathƒ_(l)(x_(l),y_(l),u_(l),v_(i)). In consideration of a plurality ofenergy directing surfaces, the plenoptic 5D function provides for threespatial coordinates x_(l),y_(l),z_(l) from a first coordinate comprisingone or more energy locations and directed through a second coordinatealong a plane comprising waveguiding parameters u_(i),v_(i) defining avector of an energy propagation pathƒ_(i)(x_(l),y_(l),z_(l),u_(l),v_(l)). For each of 4D or 5D, additionalvariables for time and color ƒ_(l)(λ_(l),t_(l)) may be considered andassumed to be inclusive of any of the plenoptic functions as necessaryfor an application even when not explicitly noted for simplicity of thefunction and discussion.

Along a first vector of an energy propagation path, a plurality ofintersection points comprising convergence of energies may occurtogether with additional energy propagation paths. At this intersectionpoint, a 3D point or depth parameter forms at location X_(l),Y_(l),Z_(l)among the plurality of energy propagation paths with the 4D or 5Dplenoptic functions, wherein the 3D point of convergenceX_(l),Y_(l),z_(l) among the plurality of energy propagation paths, wherefor each x_(l),y_(l) or x_(l),y_(l),z_(l) coordinate contained withinthe energy directing 4D surface or 5D surfaces, there is only a singleu_(l),v_(l) propagation path angle that forms between a first coordinateand the converging 3D point. The 4D functionƒ_(Z)(x_(l),y_(l),u_(l),v_(l)) or 5D function ƒ_(Z)(x_(l),y_(l),z_(l),u_(l),v_(l)) collectively define all 4D x_(l),y_(l),or 5D x_(l),y_(l),z_(l) coordinates and commensurate u_(l),v_(l)propagation paths that exist for each converging point atX_(l),Y_(l),Z_(l).

At a converging coordinate X_(l),Y_(l),Z_(l), a surface is formed andthe surface may comprise a point, volume, object or other embodimentcomprising a 3D position of converging energy propagation paths. Theprovided samples for each surface location may comprise one or moresurface properties, vectors, materials, characterizations, or otheridentifying property V_(i) to characterize or otherwise process theresulting energy, as well as one or more input energy sources striking agiven point proximate to the surface location wherein the reflectancefunction now comprises a generalized vector for the various propertiesof the surface and represented as an 11D universal objectparameterization function ƒ_(r) (λ_(i),x_(i),w_(i),λ_(r),x_(r),w_(r),V_(i)).

The 11D universal holographic parameterization functionƒ_(r)(λ_(i),x_(i),w_(i),λ_(r),x_(r),w_(r), V_(i)) defines the resultantvalues for a given environment and vectorized object properties and the4D function ƒ_(l)(x_(l),y_(l),u_(l),v_(l)) defines the energypropagation paths from an energy directing device surface, may thereforebe further generalized as an 15D universal holographic parameterizationfunction ƒ_(r)(λ_(i),x_(i),w_(i),λ_(r),x_(r),w_(r)(x_(l),y_(l),u_(l),v_(l)), V_(i))where the transmitted direction w_(r) defines and equals the propagationpath of u_(l),v_(l), whereby defining the spatial coordinate x_(l),y_(l)and for each transmitted direction w_(r) there may be only oneƒ_(l)(x_(l),y_(l),u_(l),v_(l)) set of values to satisfyw_(r)=u_(l),v_(l). Those skilled in the art will appreciate the varioustransforms and mathematical constructs in addition to the renderingrequirements associated with the disclosed universal parameterization of4D and 5D holographic sensory energy properties.

With the complete 15D function describing the vectorization of allsensory energy properties to coincide with surfaces formed fromconverging points in space, multiple orders of magnitude of requireddata have been fundamentally eliminated provisioning for a viable pathto enabling the transmission of truly holographic datasets.

The vectorized properties strive to provide accurate physics for each ofthe sensory domains for properties that may be synthetically programmed,captured, or computationally assessed, wherein V_(l) may prescribeattributes for each surface, volume or 3D coordinate X_(l),Y_(l),Z_(l)vectorized properties about an object for a given sample within aprovided dataset for general system metadata or for each or any sensoryenergy domain, comprising:
